Screen won't turn on

I have a 13th gen laptop with Windows 11, and the screen won’t turn on when I power the computer on. The lights for the keyboard all come on, the screen just stays black. I had a similar problem a couple of months ago, and resetting the mainboard seemed to fix it then, but I didn’t do anything to the computer and it started not working again. Resetting the mainboard no longer seems to fix this, so I’m at a loss for what to do. Any help would be greatly appreciated.
